Abstract (from CDS):

We have begun in 2005 a tight spectroscopic and UBVRCIC photometric monitoring of the poorly known symbiotic star GH Gem. Its absorption continuum is that of a K3III metal poor, low reddening giant, showing only weak, low ionization emission lines, with strong profile modulation. The long-term photometric evolution in V band is dominated by a marked periodicity at 331.774 day and ΔV = 0.8 mag amplitude, while a sinusoidal ΔB = 0.6 mag and P≃72.5 variability modulate the brightness at shorter wavelengths.
